Yes , additive packs are being challenged as well.

Similar usage added to oil as Seafoam I believe before an oil change. Berrymans B12 may work better as a engine flush over Seafoam though .

So , due to the oil shortage / oil situation - these are lesser quality oils being made now not as good as oils made before approx. Feb. - correct ?

Any concern for using Berrymans B12 if you are not doing an immediate oil change once gas tank is run down to empty ?

The only fair comparison should be between Mobil 1 Extended Performance and Mobil 1 Annual Protection. Then the question would be which is better if both are DEXOS approved with similar max mileage of 25,000 mile and 20,000 mile rating respectively ?

Due to Middle East oil supply challenges resulting in oil formula changes : Are North American consumers now getting a lessor quality oil than before Feb. from Mobil , Pennzoil , Valvoline , Castrol , Quaker State , etc. ?

Because of regional challenges impacting oil supply - are we getting lesser quality oils now ?

The 0W30 ESP is a very thick 30 weight while the Pennzoil Ultra Platinum is a thinner 30 weight - which your engine may prefer.

What OCI’s are you running (i.e. 5,000 miles / 6 months) with Valvoline Restore and Protect ? Also your driving conditions - city / suburb mix or mostly interstate / highway driving ?

Mobil 1 ESP rated for approx. 12K miles max while Mobil 1 Extended Performance and Mobil 1 Advanced Clean show max mileage on the jug. My Hyundai 2.4L Sonata GDI engine will never see those long OCI’s due to soot and fuel dilution.

Are Mobil 1 ESP , Mobil 1 Extended Performance and Mobil 1 Advanced Clean oils on the same level for cleaning , preventing new deposits and lastly wear protection ? * If you drive American Japanese or Korean vehicles - which would you pick from the Mobil line up for 5W30 or 0W30 or possibly...

I posted some time back in UOA section - as I recall Quaker State Ultimate Durability 5W20 wear metals were within limits but TBN was low at 4K miles . The Hyundai 2.4L HDI engine was not a good candidate to run on 20 weight oil to appease CAFE nor was it an engine suited for longer drains...

Have to say though that there are much better products that Rem Oil for firearms lube : CLP, Lucas Extreme, FP10, MPro-7and SLIP 2000 to name a few . I used Rem Oil to spray on a new recoil spring assemblies as it is light and fairly slick for that purpose but is gone after 50 rounds.

Along with Valvoline Restore and Protect usage are Microgard oil filters , top tier fuel , clean PCV valve , no engine lugging and 5 K mile max OCI’s or 6 months (which ever comes first).

I did a UOA at 4K miles with Quaker State Ultimate Durability 5W20 and the oil was spent. I switched to 5W30 (mainly Mobil 1 versions) and use 4K miles as my base line OCI now. I do like Valvoline Restore and Protect in this engine and I like the low wear numbers it puts up. However, I like M-...

I recently ran an experiment to listen for noise on Valvoline Restore and Protect 5W30 over the course of an OCI of 4,000 miles / 6 months. Vehicle is a well maintained 2017 Hyundai Sonata 2.4L GDI Theta II (non - turbo) engine. A fresh fill is very quiet in this engine running very smooth. In...

I believe internally the above two cannister oil filters quality is the same. The Advance Auto Car Quest (white) oil filter is a little more slick externally while the O’Reilly Microgard oil filter (grey) is slightly more grippy. I prefer to just grip the oil filter to remove if possible without...

I’m guessing Mobil 1 with POE = Mobil 1 Extended Performance , Mobil 1 ESP ?

Griotts has greatly expanded its auto products line including more options for auto paint . Not being familiar with them I stay with Griotts 3:1 Ceramic Sptay for everything except the front windshield .

OP : Adding 100% usage of Top Tier Gas as well to oil use strategies.
